Iwo "Mwoyo" weTricone Roller Bits: Matatu Matatu Akatakura Marudzi Anosarudza Kuchera Kubudirira

Pakutsvagisa oiri uye gasi uye geological drilling nzvimbo, iyoroller cone bitrakafanana ne“chikara chesimbi” chinopinda muvhu, uye kutakura kunoshanda so“mwoyo” wechikara ichi. Inotsigira kutenderera kwepamusoro-soro kwemakoni, inotsungirira matambudziko epasi pevhu uye kupesana, uye inogadzirisa zvakananga hupenyu hwebasa rebhiti uye kushanda kwekushanda kwekuchera. Nhasi, isu tichapwanya matatu epakati akatakura mhando dze roller cone bits, tichiongorora zvakavanzika zvehunyanzvi kuseri kwechimwe nechimwe uye mamiriro avanokunda.

I. Sliding Seled Rubber Bearing: The Cost-Effective Champion, Avimbika Mubatsiri kune Akapfava kusvika Pakati-Akaoma Formations.

Muzviitiko zvekuchera zvakajairwa, iyo inotsvedza yakavharwa rabha inobereka "murwi" ane ruzivo ane mwero wekushandisa wakakwira. Chimiro chayo hachina kuoma; iyo yepakati ine inotsvedza friction peya inoumbwa nealloy simbi jenari uye isingapfeki inodzivirira alloy bushing. Kufanana nezvikamu zviviri zvesimbi zvakakanyiwa, zvinofambisa simba kuburikidza nekutsvedza kunotsvedza. Kudzivirira kupindira kwemvura yekuchera, yakatsaurirwa rubber sealing assembly—senge radial seal mhete uye kupera gaskets—inosungirirwa kune rumwe rutivi rwekunze kwegomba rinotakura, uye mhango izere ne-high-viscosity grease kuti iite "chidziviriro chekudzivirira."

Kubatsira kukuru kweichi chibereko chiri mu "kugadzikana" kwayo uye "kudhura-kubudirira." Iyo inotsvedza friction dhizaini inogonesa yunifomu yekutakura mitoro uye yepamusoro kukanganisa kupikisa, ichiibvumira kushanda zvakatsiga kunyangwe pasi pekudzvinyirirwa kwepamusoro uye kutenderera kwekumhanya kwemamiriro. Pamusoro pezvo, inoratidzira mitengo yakaderera yekugadzira uye nyore kugadzirisa—mushure mekupfeka, bushing chete inoda kuchinjwa kuti idzorere bhiti kushanda. Nekudaro, chisimbiso cherabha ndicho "kusasimba" kwayo: kupikisa kwayo tembiricha kazhinji hakupfuuri 120.°C, uye muganho wayo wekupokana wakatenderedza 50MPa, zvichiita kuti isashande mumatsime akadzika-tembiricha kana painofumurwa nemvura yekuchera.

Naizvozvo, "nzvimbo huru yehondo" yekutsvedza yakavharidzirwa mabhengi erabha ari munyoro kusvika pakati-akaoma maumbirwo, senge ivhu, sandstone, uye limestone. Ivo vakanyanya kukodzera kuchera kumahombekombe kwakajairika,kuchera kwakananga, uye mashandiro asina kudzika matsime uko kudzora mutengo kwakakosha. Kana zvidikanwi zvako zvekuchera zvichienderana nezviitiko izvi, kubereka uku kuchave sarudzo inodhura zvakanyanya.

II. Rolling Yakavharidzirwa Rubber Bearing: Iyo Yakakwirira-Kushanda Pioneer, Chinhu Kiyi Chishandiso chepakati-Chakaoma kune chakaoma Mafomati.

Kana kuchera kuchichinja kune yepakati-yakaoma kune yakaoma maumbirwo, akadai segranite nebasalt, kugona kwekutsvedza kwakavharidzirwa mabheji erabha kunova kushoma.—uye ndipo apo kukungurutsa mabheji erabha akavharidzirwa kunotora nzvimbo yepakati. Kuvandudza kwayo kwepakati kutsiva iyo yechinyakare inotsvedza friction peya nezvinhu zvinotenderedza (bhora mabhengi kana roller bearings). Zvese zviri zviviri zvinotenderedza zvinhu uye mukati / kunze zvindori zvakagadzirwa nepamusoro-chaiyo kupfeka-resistant alloy, uku ichichengeta chisimbiso cherabha uye girisi-based sealing uye lubrication system.

Shanduko inonyanya kukosha inounzwa nekukweshana ndeye "kudzikisira kuedza": kupikisa kuramba kunodzikiswa zvakanyanya,chidimbu chachokutanga torque idiki, uye inogona nyore kuwana yakakwirira kutenderera kumhanya. Kumhanyisa kwemakanika kudhirowa kunowanzo wedzera ne10% -30%, inova pasina mubvunzo mukana mukuru wemapurojekiti ari kutsvaga kuchera kwakanyanya. Zvisinei, inotorawo miganhu yezvisimbiso zverubha—tembiricha yayo yakanyanya kuramba yakakwira zvishoma pane iyo yekutsvedza mabhengi, asi inongosvika 130°C, ine simba rekudzivirira rinosvika 60MPa. Uyezve, izvo zvinotenderedza zvinhu zvine hanya zvakanyanya kune tsvina; zvimedu zvakasimba mumvura yekuchera zvinogona kukonzera jamming zviri nyore, saka zvinodiwa zvepamusoro zvinoiswa pakuchena kwemvura yekuchera.

Zvichienderana nehunhu uhwu, rolling yakavharwa rubber bearings inonyanya kushandiswa kuchera mukati-yakaoma kusvika kune yakaoma maumbirwo, senge vertical zvikamu zvematsime akadzika uye akadzika-akadzika, pamwe nehunyanzvi hwekuchera mapurojekiti anoda kukurumidza kudhirowa kwemichina. Panyaya yekuchera kusarudzwa kwemvura, ivo vanonyanya kuenderana nemvura yakachena uye yakaderera-yakasimba-chikamu chekuchera mvura masisitimu. Kupa kutamba kwakazara kune yavo yepamusoro-yakanaka zvakanakira, kushandiswa kwemvura yekuchera ine yakakura yakasimba masisitimu inofanirwa kudziviswa zvakanyanya sezvinobvira.

III. Yasina Kuvharwa Rolling Air Bearing: Iyo Yepamusoro-Tembiricha Inodzivirira Nyanzvi, Iyo Yakasarudzika Sarudzo yeYakasarudzika Kuchera Maitiro.

Mune tembiricha yepamusoro-yepamusoro uye yekupedzisira-yakanyanya kudzvanya yakadzika yekuchera mamiriro, senge geothermal matsime uye shale gasi matsime akadzika, zvisimbiso zverabha zveekutanga maviri anotakura marudzi anotadza nekuda kwekupisa kwakanyanya. Panguva ino, iyo isina kuvharwa inotenderedza mhepo inove ndiyo yega mhinduro inoshanda. Dhizaini yayo yakasarudzika yakasarudzika: inotora inotenderedza element friction pair asi inobvisa zvachose musangano wekuisa chisimbiso. Iyo inotakura mhango yakabatana zvakananga kune yekuchera svikiro, uye yakakwira-kudzvanywa mweya kana atomidhi yekuchera mvura inoshandiswa senge inotonhorera uye yekuzora svikiro.

Pasina zvisimbiso zvezvisimbiso, kushomeka kwayo kwekushisa kwawana kusvetuka kwemhando, inosvika pamusoro pe200.°C, iyo inokwanisa zvizere kuchinjika kune yakanyanya-yepamusoro tembiricha yepasi pevhu. Panguva imwecheteyo, mweya wepamusoro-soro unoramba uchichenesa gomba rinotakura, kwete kungobvisa kupisa kunokonzerwa nekukweshana asiwo zvinobudirira kudzinga kucheka kwemukati kuti usatakura kupfeka, kuvandudza zvakanyanya kuvimbika munzvimbo dzakaoma. Nekudaro, ine zvakare yakasarudzika "zvinodikanwa": ine zvakanyanyisa kudiwa pamhepo yekugovera sisitimu, inoda yakagadzikana yakakwirira-inomanikidza mweya sosi. Uyezve, hupenyu hwekubereka hunokanganiswa zvakananga nekuchena kwemhepo—kana tsvina ikasanganiswa mumhepo sosi, inogona kukonzeresa kukuvara zviri nyore.

Rudzi urwu rwekubereka rune hunyanzvi hwekushandisa, hunonyanya kushandiswa mukupisa-kwepamusoro-tembiricha uye kwekupedzisira-kumanikidza kwakadzika kuchera mutsime, pamwe chete nematanho akakosha akadai sekuchera pasi uye kudhiraivha kwemhepo. Mune maitiro aya, mhepo inodzvanywa haingopi lubrication uye kutonhora kwekutakura asiwo zvinobudirira kudzivirira kudonha kwetsime, kuzadzisa zvinangwa zviviri kamwechete. Izvo zvinofanirwa kucherechedzwa, zvisinei, kuti hazvienderane zvachose neyakajairwa mvura-based drilling fluid masisitimu uye inogona kungoshanda mugasi kana atomidhi yekuchera fluid media.—iyi ndiyo misimboti yayo yekushandisa.

Pfupiso: Ungasarudza sei Pakati peMatatu Bearings? Kufananidza Mamiriro Ekushanda Ndiwo Kiyi

Pashure pokudzidza nezveudzame hweaya mabheya matatu, zviri pachena kuti hapana ukuru hwakakwana kana kuti kudzikira pakati pawo.—misiyano chete mukukodzera kune chaiwo mamiriro ekushanda. Nemashoko akareruka, iyo yakakosha logic yekusarudza inogona kupfupikiswa mumapoinzi matatu:

Pamaumbirwo akapfava kusvika epakati-akaoma uye mashandiro emutsime asina kudzika apo mutengo-unobudirira uri pamberi, sarudza inotsvedza yakavharwa rubber bearing; kune yepakati-yakaoma kusvika kune yakaoma maumbirwo apo yakakwirira yekuchera uye kushanda zvakanaka kunodiwa, sarudza rolling yakasimbiswa rubber bearing; uye kune yakanyanya-yakakwirira tembiricha, ekupedzisira-yakanyanya kudzvanya matsime akadzika kana maitiro akakosha senge kudhirowa kwemhepo, iyo isina kuvharwa inotenderedza mhepo inotakura ndiyo yega sarudzo.

Se "moyo" weiyo roller cone bit, kutakura kusarudzwa kunobata zvakananga mutengo, kunyatsoita, uye chengetedzo yekuchera mabasa. Zvinotarisirwa kuti chinyorwa ichi chichakubatsira iwe kujekesa musiyano mukuru pakati pemabheya matatu, zvichiita kuti usarudze "moyo" wakarurama wemapurojekiti ekuchera uye kuve nechokwadi chekuchera kwakanaka uye kwakavimbika nguva dzose.
